Alps SKCL Lock is a alternate action switch in the first and second generation of the Alps SKCM/SKCL Series.

Characteristics

The switch follows the general characteristics of the SKCL family, consisting of an upper and lower housing, contact module, stem, and spring. There is a follower arm that moves along the slider to generate a locking action wherein the switch stays depressed until pressed again.

There are two switches in the series, both largely identical aside from contact module and materials:

  • SKCLJB - A cream-colored SKCL Lock switch in the first generation
  • SKCLJC - A gray-colored SKCL Lock switch in the second generation

Alps SKCL Lock, like all SKCM/SKCL series switches, uses a contact module to register the keypress. This sits in the housing on the side without the LED cutout.

Additional Information

The switch was likely in production from 19831) to the late 1990s.
